It is possible to build gcc with support of weak symbols which will fix 
problems with static members in template classes (see message from 
Mark Elbrecht from 23 March 1999 in djgpp-workers).

Main problem:
	one will have to use development snapshots of binutils (
        binutils 2.8.1 and 2.9.1 doesn't support weak symbols for DJGPP)

If there would be easy way how to enable/disable it from specs it 
perhaps would be acceptable.
